This paper investigates controllability and observability of linear time-invariant uncertain systems. For a certain class of linear uncertain systems, it has been shown that a system is controllability and observability invariant if and only if the system has a particular structure called a complete generalized antisymmetric stepwise configuration (CGASC). In this paper, a new class of systems is introduced in order to investigate the dual property between controllability and observability.
